Deeper analysisAI
CVE-2025-8830 is an OS command injection vulnerability affecting Linksys Wi-Fi range extenders, specifically models RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 running firmware versions up to 20250801. The flaw exists in the sub_3517C function of the /goform/setWan file, where manipulation of the Hostname argument enables arbitrary command execution on the underlying operating system. Published on 2025-08-11, it carries a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) and maps to CWE-77 (Command Injection) and CWE-78 (OS Command Injection).
The vulnerability can be exploited remotely by an attacker with low privileges, such as an authenticated user on the device. No user interaction is required, and the low attack complexity allows straightforward exploitation over the network. Successful attacks enable limited impacts on confidentiality, integrity, and availability, potentially allowing command execution within the context of the vulnerable web interface.
Advisories from VulDB indicate that the vendor was contacted early regarding the issue but provided no response. A proof-of-concept exploit has been publicly disclosed on GitHub, increasing the risk of active exploitation. No patches or official mitigations are referenced in the available sources.
